Nationwide cable television operator Gala Television Corporation (GTV) have adopted the Microvideo HDS 201s seamless switch, in their Taipei facility. The unit is used to switch between the main Sony video router and a back-up feed to ensure uninterrupted viewing of some of Taiwan’s favourite game shows.

The Singapore Parliament have purchased the Microvideo HDK 300 Down stream keyer which is used as part of the Parliament’s in-house video production facility to key graphics generated from an external HD character generator inside the Chamber during the actual Parliament Sittings.

Kenny Phua of PTL explains: “Before the introduction of the HDK 300 Keyer, the video displayed on the large video displays in the House Chamber had a latency of almost one second which was very disturbing to the Members of the House. We assisted the House in removing the video latency with the use of HDK300 by demonstrating that there was negligible propagation video signal latency between the input and output of the Keyer. It is a relatively simple install, but we gave the House full satisfaction in removing the latency and they enjoy crisp HD video quality.”

Cable operator PCCW has acquired a Microvideo HDB 300 to decode WSS cues on delayed news transmissions that are broadcast over the border into Southern China.

The News room and MCR are located in different parts of Hong Kong, so needed a way of remotely controlling play out so that the appropriate sections of programme are censored as required by the authorities. A cue to trigger the censored output was inserted into the VBI space before being sent to the MCR. At the MCR, the cue is decoded by the HDB 300 which then provides a tally signal to enable equipment which blocks transmission of the specific news item.

By no means an exhaustive look at Data Types used in Broadcast, this document does however, set out to cover some of the more common uses of data and terms used in describing those data types and uses. There is a whole area not covered by this short introduction which is 2nd screen and audience monitoring. These are areas where a book could not suffice, however, there are plenty of articles and descriptions on Microvideos website and should you require any specific information then please call us.
